appliance or reventing the window pane fromfrosting ue to a different temperature between the outer side of the window pane and the inner side.

Another object of my invention is to provide an appliance that can be advanta-v geously used in connection with therwindows of street cars and similar vehicles, where the frost u on the window often obstructs the view 0 the motorman or occupants of the car.

A further object-of this invention is to furnish a window frame with an ap liance that will remove frost and snow, t e a pliance being simple in construction, app icable to WlIlClOW frames of electricall driven vehicles or vehicles provided wit storage batteries, durable, and highly eflicient for thepurposes for which it is intended. These and such other objects as may herenafter appear are attained by the novel construction, combination and arrangement of parts to be hereinafter specifica ly descri ed and thenclaimed.

eference will now be had to the draw-- in forming a art of this specification w erein there is 1 lustrated a preferred ern bodiment of the invention, but it isto be un-. derstood that the structural elements thereof can be varied. or .changedjwithout de-. parting. from the spirit and'scope of the lnvention. j

In the drawings Fi re 1 is a front ele-r ame provided with my improved appliance. Fig. 2 is a vertical sectional view of the same. Flg. 31s an enlarged vertical sectional view of a por- .tion of thewindow frame, and, Fig. 4 isan enlarged longitudinal sectional view of a portion of the appliance;

' In the accom anymg drawings the refer- I ence numeral 1 enotes a window frame supportinga pane or plate of glass 2. The

' 4 is applicable t various ty frames or sashes y making t e same of vaframe 1 may representa window sash and as either a sash or frame, the to and bottom rails thereof are provided. with clips 3 adapted to support theupper and lower ends of a metallicframe 4, said frame being shaped as a molding with the upper end thereof provided with a plurality of vents or apertures 5. The frame 4has. the

inner edges thereof bent to form channelshaped holders 6 for an outer pane. or plate of glass 7, this ane of glass being sufficiently removed rom thepane of glass 2 to form a compartment 8 upon the-outer side' of the window frame or sash 1.

The lower end of the metallic frame 4 is shaped to form a cylindrical casing 9 ap proximately the length of the lower end of the frame 4, said'casing having the rear wall 10 thereof attached to the frameor sash 1 through the medium of hooks '11 adapted to engage in slots 12 formed in the rear, wall 10 of the casing 9. The inner sides of, the easing 9 are lined with asbestos 13 or other nonoonductive and non-fusible material. The casing 9 forms a compartment 14 at the lower edge of the frame 4 communicating with the "compartment 8, and in the cgmpartment 14 is locatedan'electric beaten/comprising a coil 15 adapted to be connected to a suit-ablesource of electrical energy, whereby the coil will furnish the compartments 14 and 8 with suflicient heat units to heat the panes of glass 2 and! and prevent frost or snow from accumulating u on the outer side of the paneof glass 7. T e electric heater is of a conventional form and the compartment 14 will accommodate various types of light and durable metal coated or otherwise,

finished to prevent corrosion, and the frame' of window rious sizes.

What I claim, is 1. In"a window a pliance, the combination with a window ame having a pane of glass mounted therein, of a frame connected to said window frame and havingits lower ried by the window frame and engaging the portion benttoprovide a'casing, means carportion bent 'to provide a casing, means carried by the window frame and engaging the bent portionof said frame for connecting said bent portion in position, a pane of glassu carried by said frame and forming in connection with the pane of glass carried by the window frame a compartment, and a heater arranged in said casing and adapted to heat the compartment formed by said panes of glass. v

2. In a window appliance, the combination with a window frame having a pane of glass mounted therein, of a frame connected to said window frame and having its lower portion bent to'provide' a casing, means car- .bent portion of said frame for connecting said bent portion in position, a pane of'glass carried by said frame and forming in connection with the pane of glass carried by the window frame a compartment, a heater arranged in said casing and adapted'to heat the compartment formed by said pan'es of glass, and-said frame having its upper portion provided with means to constitute vent openings.

3. In a window appliance, the combination with a window frame having a pane of glass mounted therein, of a frame connected to said window frame and having its lower ried bv the window frame and engaging the bent portion 'of'said frame for connecting said bent portionin position, a pane of glass carried by said frame and forming in connection with the pane of glass carried by the window frame a compartment, a heater ar-' ranged in said casing and adapted to heat the compartment formed by said panes of glass, and a linin of non-conductivemate rial for the inner ace of said casing.

at. In a window appliance, the combination with a window frame having a pane of glass mounted therein, of a frame connected to said window frame and having its lower portion bent to provide a casing, means carried by thewindow frame and engaging the bent portion of said frame for connecting frame providedatits upper portion with.

means to-constitute vent openings.

'5. In a window appliance, the combination with a window rame having a pane of glass mounted therein, of an auxiliary frame secured to said window frame and carrying a pane of glass, said panes of glass opposin each other and forming a com artment, said auxiliary frame having its ower portion bent to provide a casing having its interior thereof communicating with said compartment, hooks carried by the window frame for connecting the bent ortion of the auxiliary frame thereto, an a heater arranged in said casing for heating the compartment formed by the Cpane of glass.

6. In a win ow a pllance, the combination with a window rame having a pane of glass mounted therein, of an auxiliary frame secured to said window frame and carrying a pane of glass, said panes of glass opposin each other and formlnga coin artment, sai
